Timer V2 Leds

thingiverse

I was searching for a Minuteur / Timer to help my 6-year-old son understand and save time (homework, shower, etc.). I stumbled upon this project: https://wikifab.org/wiki/Timer:_A_Timer_Based_on_Arduino I immediately agreed. But I didn't have a laser cutter. I decided to create a case for the electronics. The 24 color LEDs allow you to see how much time is left. It's based on Arduino. By default, there are 1min, 3min, 5min, 10min, 15min, 20min, 30min, 45min, 1h, 1h30, and 2h options. You can add or remove them. You can power it with a phone charger or an external battery. You can also use a 9V battery with its cord. I used a complete Arduino kit: https://www.amazon.fr/dp/B01JD2Z5XW/ref=cm_sw_r_tw_dp_U_x_hiFHEbBYV8C62 And some LEDs: https://www.amazon.fr/dp/B07QLMPV6S/ref=cm_sw_r_tw_dp_U_x_ghFHEbN1VBA5W I used 4 M3x4mm screws with nuts that I glued in the case beforehand. Assembling the timer: Put the electronics into the case Slide the small printed plate between the buttons (from the electronic part) and the case. Glue the buttons (printed) onto the plate, passing through the case hole.
